Description
The Eaton Bussmann 315NHG1B is a high-performance low-voltage DIN-type NH dual fuse link rated at 315A in NH size 1 form factor. Classified as gL-gG under IEC 60269 and DIN EN 60269, this fuse link delivers full-range overcurrent protection suitable for both cable and general load applications. Its dual fuse element design enhances protection reliability, making the 315NHG1B a trusted choice wherever consistent and precise fault interruption is required in low-voltage power distribution systems.
The 315NHG1B is widely deployed in low-voltage switchgear panels, main and sub-distribution boards, motor control centres (MCCs), and cable feeder circuits in industrial plants, commercial buildings, and infrastructure projects. Its 315A rating makes it particularly well suited for protecting large motor feeders, transformer secondaries, busbar tapping points, and outgoing feeder cables in installations where high continuous load currents are present alongside the risk of sustained overloads or short-circuit faults.
Engineered to the DIN-type NH form, the 315NHG1B offers a high breaking capacity that safely interrupts prospective fault currents in low-voltage networks. The dual fuse element construction provides a degree of redundancy and improved arc-quenching performance, ensuring controlled disconnection without damage to surrounding equipment. Full compliance with DIN EN 60269 and IEC 60269 guarantees interoperability with standard NH size 1 fuse bases and holders across all major switchgear platforms used in India and globally.
Eaton Bussmann is recognized worldwide as a leader in circuit protection technology, with decades of engineering expertise trusted by original equipment manufacturers, panel builders, consulting engineers, and electrical contractors across more than 100 countries. Every Eaton Bussmann fuse link, including the 315NHG1B, is manufactured under rigorous quality controls and tested to international standards, ensuring predictable performance, long service life, and compliance with project specifications and statutory safety requirements.

What does NH size 1 mean in fuse 315NHG1B?
NH size 1 refers to the standardized physical dimension of the DIN-type fuse link as defined under DIN EN 60269 and IEC 60269. Size 1 specifies the blade contact geometry, overall body dimensions, and the current rating range the fuse can safely handle, ensuring compatibility with all NH size 1 fuse bases, switch-disconnectors, and holders from any compliant manufacturer.
What does class gL-gG mean for the 315NHG1B?
The gL-gG classification is a general-purpose fuse class defined by IEC 60269. The letter g indicates full-range breaking capacity, meaning the fuse can interrupt all fault currents from the minimum fusing current up to its rated short-circuit breaking capacity. The designations L and G indicate protection of cables and conductors as well as general electrical equipment including motors, transformers, and distribution circuits, making the 315NHG1B suitable for a broad range of low-voltage protection applications.
What are the typical applications for the 315NHG1B?
The 315NHG1B 315A NH1 dual fuse link is commonly used in low-voltage switchgear panels, main and sub-distribution boards, motor control centres, transformer secondary protection, busbar tapping units, and outgoing cable feeder circuits in industrial manufacturing facilities, commercial complexes, data centres, and infrastructure projects where reliable overcurrent and short-circuit protection is essential.
What is a dual fuse link and why does the 315NHG1B use this design?
A dual fuse link incorporates two fuse elements within a single fuse body. This design improves arc-quenching efficiency, enhances thermal stability under sustained overload conditions, and provides more consistent tripping characteristics across the full current range. For a 315A rated device like the 315NHG1B, the dual element configuration helps manage the higher energy levels involved during fault interruption, resulting in safer and more reliable disconnection.
Is the 315NHG1B compatible with standard NH size 1 fuse holders available in India?
Yes. The 315NHG1B is manufactured to DIN EN 60269 and IEC 60269 dimensional and performance standards, making it fully compatible with any compliant NH size 1 fuse base, switch-fuse unit, or fuse switch-disconnector available in the Indian market, regardless of the switchgear manufacturer.
